xalanc: ICUBridge::FormatNumber

[David Braaten <da...@multiactive.com>]

I made a small change to ICUBridge.cpp, ICUBridge::FormatNumber,  to check
for
U_USING_DEFAULT_ERROR, because it is a valid status code...

(I hope someone will excuse my laziness and check this change into the
source tree... ;)  )

unsigned long
ICUBridge::FormatNumber(
   const UTF16VectorType&  thePattern,
   double      theNumber,
   UTF16VectorType&   theResult)
{

 const UnicodeString  theUnicodePattern(&thePattern[0], thePattern.size());

 UErrorCode    theStatus = U_ZERO_ERROR;

 UnicodeString   theUnicodeResult;

 DecimalFormat   theFormatter(theUnicodePattern, theStatus);

 if ( theStatus == U_USING_DEFAULT_ERROR )
 {
  //translate default to zero error because it's expected by
  // callers and it's ok to be using the default.
  theStatus = U_ZERO_ERROR;
 }

 if ( theStatus == U_ZERO_ERROR )
 {
  // Do the format...
  theFormatter.format(theNumber, theUnicodeResult);

  const int32_t theLength = theUnicodeResult.length();

  // Resize the vector to the appropriate length...
  theResult.clear();
  theResult.resize(theLength);

  theUnicodeResult.extract(0, theLength, &theResult[0]);
 }

 return theStatus;
}
